BKH Ball Valves/BKH3K Ball Valves Exporter introduced that the pneumatic ball valve only needs to enter the pneumatic actuator through compressed air, and the air source drives the ball core to rotate 0-90 degrees and a small turning torque can control the opening and closing of the ball valve, which can be controlled according to the working conditions. It is required to install a valve positioner to control the opening of the ball core of the ball valve to adjust the flow of the medium. The ball rotates around the center line of the valve body to achieve opening, and there are circular through holes or channels passing through its axis. When the ball center rotates to 90°, the valve is in a tightly closed state. When the actuator is working, the valve can be tightly closed with only a small turning torque, so as to achieve the principle of rapid cut-off.

Working principle diagram of pneumatic ball valve (1. Pneumatic head 2. Solenoid valve 3. Filter pressure reducing valve 4. Air source) Figure 2 is the working principle diagram of a set of single-acting pneumatic ball valve, the same as before, the compressed air first passes through the filter pressure reducing valve , When the solenoid valve coil is energized, the gas flows into the solenoid valve air inlet a port, from the gas port b to the pneumatic head, pushes the piston to move, and the inner spring of the pneumatic head is compressed. The solenoid valve returns to the spring position, the air source is blocked, the pneumatic head spring releases the compression force, and pushes the piston to move in the opposite direction. The exhaust channel is b~c, which can keep the ball valve in the set open or closed position to prevent accidents.
